Note 2: The maximum rating is defined as above based on the chamber temperature, which might be

different from ambient temperature after assembling the panel into the application. Moreover, some temperature-related phenomenon as below needed to be noticed:

6. OPTICAL CHARACTERISTICS

The optical characteristics are measured based on the conditions as below:

- Supplying the signals and voltages defined in the section of electrical characteristics.

- The backlight unit needs to be turned on for 30 minutes.

$

- The ambient temperature is 25

- In the dark room around 500~1000 lx, the equipment has been set for the measurements as shown in Fig 6.1.

Note 3: The Contrast Ratio is measured from the center point of the panel, P5, and defined as the

following equation:

CR

Whiteof Brightness

Black of Brightness

Note 4: The definition of response time is shown in Fig. 6.3. The rising time is the period from 10%

brightness to 90% brightness when the data is from black to white. Oppositely, Falling time is the period from 90% brightness falling to 10% brightness.

Fig 6.3

Note 5: The definition of viewing angle is shown in Fig. 6.4. Angle I is used to represent viewing

directions, for instance, angle

is used to represent viewing angles from axis Z toward plane XY.

I

means 6 o’clock, and

The display is super wide viewing angle version, so that the best optical performance can be

obtained from every viewing direction.
